Table 8 compares the number of known species with the approxi- 

 mate areas and peak elevations for each island. According to other 

 studies made of island floras (Cain, 1944:215-220), we could expect the 

 islands with more numerous species to be correlated with ( 1 ) greater 

 island area, (2) islands with higher elevations, (3) complex physiogra-

 and elevation of the respective gulf islands. Areas have been computeed on the 

 basis of approximate measurements and can only be considered relatively.
